Doctors Order Good Night's Sleep

3/20/2012 BEIJING (Xinhuanet) -- More than 40 percent of
Chinese people suffer from sleep disorders, but less than 1 percent have
been diagnosed or treated, experts said.

Working people, particularly shift workers in cities who have fast-paced
lifestyles, have the highest risk of sleep problems, said Han Fang,
director of the sleep center under the Peking University People's
Hospital and vice-president of the Chinese Sleep Research Society
